This type of natural selection is referred to as directional selection. In this type of natural selection, either one phenotype is preferred or the other; therefore, there is no equilibrium between the populations of the phenotypes that are present.
Examples of organisms that have undergone directional selection are black bears during the ice ages, African chichlid and sockey salmon.

<span>The answer is B. Brain drain means a country is losing its professionals to the external market rather than working in the local market due to unfavorable local conditions. The country loses because it has few medical professionals to treat its people hence it carries a higher burden of diseased people. Additionally, to cater to this gap, it has to import these medical services which is more expensive than keeping local talent. </span>
Answer:
The correct answer will be -
1. ATP production- Thylakoid membrane
2. Activated carrier- NADPH.
Explanation:
The photosynthesis reactions take place in the chloroplast which is divided into three membranes: outer, inner and thylakoid membrane. The light-dependent reactions take place in the thylakoid membrane which helps in the production of ATP molecules along with the activated carrier molecule called NADPH.
The ATP molecule is synthesized by the ATP synthase enzyme located in the thylakoid membrane where electron transport chain produces a gradient of protons. These protons help in the production of ATP synthesis explained through the chemi-osmotic model.
Thus, the Thylakoid membrane and the NADPH are the correct answer.
